SPECIFICATION forming part of Letters Patent No. 455,691, dated July 7,1891,.

Application led December 16, 1890. Serial No. 374,874. (No model.)

.To all w/wm it may concern: Be it known that I, CHARLES S. REED, oBoston, county of Suffolk, State of Massachu-v setts, have invented auimprovement in Sewing-Machines, of which the following descrip-k tion,in connection vwith the accompanying drawings, is a specification, likeletters and figures on the drawings representing like parts.

This invention has for its obj ect to provide a sewing-machine of thewax-thread variety, using an awl and hooked needle, with means formoving laterally the material being stitched while the needle and awlare out of the material, whereby an overedge-stitch is made with asingle thread.

The machine herein to be described is Very useful for applying a fibrousor cloth binding` or edge to a wooden or other frame for a slate,

v2o and it may be used to great advantage in overstitching other heavyarticles.

In the machine to be herein described the stitch-forming devices,including the needle,

cast-off, awl, and thread-guide, are substan- 2 5 .tially as common.With these common parts I have combined a work holder which is movedlaterally by a cam on the main shaft below the bed-plate, the saidholder consisting,vessentially, of a bottom or base plate, a 3opresser-foot or equivalent capable of vertical movement, a linkconnecting it with a stand, av stud on `the said plate, and preferably agage attached to and moving with the said work-holder. The face of thisgage is notched or cut out equal to the length of the longest stitch tobe made, so as to let the needle in its horizontal or feeding movementmove outside the edge of the material.

The particular features in which my inven- 4o tion consists will behereinafter described, and pointed out in the claims at the end ofl thisspecification.

Figure l is aefront end elevation of a sewing-machine embodying myinvention, the material being omittedfrom under the presserfoot; Fig. 2,a side elevation partially broken away; Fig. 3, a top or plan View ofthe workholder below the irregular dotted line oc, Fig. 1; Fig. 4, adetail in side elevation of the parts shown in Fig. 3; Fig. 5, a top orplan View 5o like Fig. 3, but with the parts in different positions.Figs. G and 7 show the two cam-hubs developed. Fig. 8 shows materialbound and overstitched by the machine herein to be described, and Fig. 9a detail showing the guide `55 f2 detached.

The frame-work consists, essentially, of the casting A, the post A', theplate A2, the overhanging arm A3, and head A4. The head has bearings forthe awl-bar B, having the awl l) 6o and the presser-bar B. The casting Ais provided at its front end with a dovetailed groove (see Fig. 2) forthe reception of the feed-slide B2, provided with the guide B3, in whichreciprocate the needle-bar B4, having a hooked needle b4, and a cast-offB5, having secured to its upper end any usual cast-off.

C is the thread-guide shaft, having the at# tached thread-guide c.

The awl-bar derives its vertical movements 7o` from an elbow-lever B7,pivoted atBS. The parts so far speciiically referred to by letter areold and common inwell-known waxthread sewing-machin es for leather-work,and in practice they will and may be actuated in any usual manner tocause the awl to penetrate the materialfor the passage of the hookedneedle through the material and to enable the needle to feed thematerial, and in practice the presser-foot will be automatically lifted8o by usual devices acting on the lever b5 to lift it from thematerialduring the time that the needle in the material acts to feedlthe same. These parts, being old and common in the socalled New Englandwax-thread sewing-ma- 8 5 chine, need not be herein more fully describedfurther than to say that the thread on its way to the thread-guide cmaybe waxed, oiled, or treated in any usual way and be subjected to theaction of any usual tension de- 9o vice or take-up.

The casting A has suitable bearings for the main rotating shaft D,havinga cam B9, shaped, as best shown at 2, Fig. 7, to afford a slightdwell in the awl-bar, as when the holder to be described is beingshifted laterally. The main shaft has applied to it a second cam-hub D',which receives a roller or other stud D2, ex-

tended downward from the under side of the bottom plate e, constitutingpart of the holder for the material. The other effective part of theholder consists of a presser-foot c', having, as represented, astud-screw e2 (see Figs. l and 3) and a link c3, connected with the saidl screw, and a stud-screw e4 in a stand e5, at-

tached to the said bottom plate. This bottom plate also has connected toit by screws f the I binding m of felt or other desired fibrousmaterial. The machine herein described may, however, be used tooverstitch any heavy materials wherein it is desired to cover the edgewith a single thread stitched eitherpwith or without a binding. The dogg, held in place by the screw g, serves to keep the bottom plate down inproper place in its guideways in the table-plate A2.

In this invention the gage]2 is attached to and so as to travellongitudinally with the work-holder, and the edge of the material to bestitched is placed against the edge of the gage.

Assuming that the material to be stitched has been placed upon thework-holder next the face of the gage f2, the presser-foot at such timebeing lifted in usual manner and the binding m" having been placedbetween the edge of the material to be overstitched and the face of theedge-guide, and that the work-holder has been drawn back fully to theright, as in Figs. l and 2, andthe machine started, the awlb willdescend to` punch a hole nearly through the material and through thebinding thereon, and then the awl will commence to rise and the needlewill follow closely the pointof the awl and complete and rise throughthe hole made thereby and above the presser-foot, at which time thepresserfoot will be slightly lifted and the needle-bar will be moved inusual manner by the usual devices common to needle-feeding machines tofeed the material for the length of a stitch. The material having beenfed the length of a stitch, the presser-foot closely descends again uponthe material, it having a rising motion given to it in any usual mannerto enable the vfeed to take place, and the threadguide is then movedforward, so as to deliver its thread into the hook of the needle, whenthe latter commences to descend and draws a loop of needle-thread downthrough the material, the thread-guide being retracted in usual mannerand by usual devices common to wax-thread sewing-machines as the needlecompletes its descent. As soon as the needle descends through thematerial, taking with it a loop of thread which it yet holds, theworkholder, by or through its actuating-cam D', is moved to the left,the needle yet holding the loop of needle-thread below the material, andthe movement of the holder to the left having been completed and theneedle-bar having in the meantime again been moved forward toward thefront of the machine into its starting-point preparatory to rising theneedle is again raised, yet holding upon its shank'the last loop ofthread pulled down by it and the needle is again moved in the directionof the feed of the material; but at this time the needle does not enterthe material, but stands at one side of the material with its hook abovethe presser-foot, as before. During this second backward movement of theneedle. in the direction of the feed the needle does not move thematerial, but it does act upon the needle-threadbetween thethreadguideand the material at the stitch-making point and pulls the said threadback in the direction of the feed, and the needle having completed itsbackward stroke the threadguide again supplies its thread to the needle,which latter pulls a second loop of thread down through the loop then onits shank, the second loop to be pulled down lying, however, outside theedge of the material. The needle having completed its descent as before,the work-holder is again moved, this time to the right to place thematerial again in position to be penetrated by the awl and needle. Theonly time that the presser-foot is lifted from the material is when theneedle in the material is moving it to feed the same for the length of astitch. At all other times the presserfoot bears upon the material andholds it down in place upon the lower member e of the workholder. Thecam-groove in the cam B9 is of such shape at the points 2 2 as to giveto the awl a slight dwell or to slow down its movement sufficiently topermit the work-holder to be moved laterally without interfering withthe awl, this slight dwell or slowing down of the speed of the awladding very materially to the value of my invention.

I claim- A sewing-machine containing the following instrumentalities,viz: an awl-bar having an awl, a lever to move the said awl-bar, therotating shaft I), having a cam B9, to actuate the said lever, and asecond cam D', athreadguide, a needle-bar, a hooked needle,aco-operating cast-off, a presser-bar, and a workholder consisting,essentially, of a presser-foot connected with the presser-bar, a bottomplate e, the link e3, pivoted thereto, the edgeguide attached to thesaid bottom plate and havingv a cut-away portion in its face, and a studor finger attached to the bottom plate and actu- IOO ated by the Saidearn D, the needle moving name to this specification in the presence ofin said eut-away portion in itssecond ascenty two subscribing Witnesses.in the direction of the feed, but not in themal terial, to' therebyengage the needle-thread CHARLES S.
